SITUATION

The customer may complain of various failures associated with the sunroof or sliding headliner. If components of the sunroof are damaged, it was previously necessary to replace the entire sunroof cassette assembly, since separate components were not replaceable.

CORRECTION

Separate replacement parts and repair procedures have been developed for vehicles produced prior to September 2003.

Note:
A modified sunroof cassette assembly, including the sliding headliner and drive components, was introduced on vehicles produced from September 2003.

PROCEDURE

Remove the sunroof glass per Repair Instructions RA 54 12 115.





Check the slide driver (2) for damage. If no damage is visible, check the vertical clearance as follows:

Carefully insert a feeler gauge (1) under the slide driver (2) and check the vertical clearance between the driver and the guide rail (3).

Test Result

The slide driver is not damaged and the vertical clearance is less than 2.5 mm.
